The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
With reference to Fig. 1, it is the method workpiece spindle 1 to be processed that the utility model utilizes radial drilling machine grinding shaft class part centre bore, center, two ends at workpiece spindle 1, be respectively arranged with workpiece spindle centre bore 2, it is the technological datum in workpiece spindle 1 process, in the process of workpiece spindle 1, to utilize workpiece spindle centre bore 2 to carry out clamping, and realize the polishing to workpiece spindle centre bore 2.
With reference to Fig. 2, the utility model utilizes the device of radial drilling machine grinding shaft class part centre bore to be, comprises lower top 4 and support 5 on the base 3 that is fixed on radial drilling machine, is arranged on grinding on the main shaft 6 of radial drilling machine top 7, and an auxiliary centering axle 18.
With reference to Fig. 3, Fig. 4 and Fig. 5, support 5 structures in the utility model device are, comprise upper plate 8 (the present embodiment is square opening) with central opening, with the lower plate 9 (the present embodiment is demifacet round mouth) of central opening, upper plate 8 and lower plate 9 are welded by many isometric steel pipes 10 (the present embodiment is 5), and lower plate 9 lower surfaces are fixedly installed a plurality of supporting legs 11 (the present embodiment is 5); Upper plate 8 upper surfaces are symmetrically arranged with the movable steel plate 13 of three place's fixation steel plates 12 and a place along central opening surrounding, three place's fixation steel plates 12 are all fixedly welded on upper plate 8 upper surfaces, movable steel plate 13 is connected across upper plate 8 openend both sides by two step pins 14, and each fixation steel plate 12 and the centripetal position of movable steel plate 13 all have screw and are separately installed with one group and hold out against screw 15.
The central opening of upper plate 8 and lower plate 9 is in order conveniently to pack workpiece spindle into, and in order to pull down with easy for installation, step pin 14 should adopt larger matched in clearance with its installing hole.
With reference to Fig. 6, lower top 4 are socketed to form by top body 16 and dead head 17, and the assembling of top body 16 and dead head 17 adopts interference fits, top body 16 adopts the materials such as T8 to manufacture, quenching hardness should be greater than HRC55, and to increase wearability, the common steel plate of dead head 17 use is manufactured.
With reference to Fig. 7, in order to coordinate above-mentioned the utility model device, also be manufactured with a prefabricated component and be called centering axle 18, centering axle 18 is close with the size of diameter, length and the two ends centre bore of workpiece spindle 1 to be processed, precision when guaranteeing centering, centering axle 18 should strictly be controlled the cylindricity of its cylindrical when making, and the datum hole at centering axle 18 two ends should have higher axiality with cylindrical centering axle, to be not more than 1/3rd of workpiece precision prescribed, is advisable.
Grind top 7 finished products that adopt on current tool markets, note its taper shank specification should with the main shaft 6 of used radial drilling machine on spindle hole specification good fit.
The utility model utilizes the method for radial drilling machine grinding shaft class part centre bore, utilizes above-mentioned device (lower top 4,5, one centering axles of support 18 and grind top 7), according to following steps, implements:
Step 1, according to Fig. 8, by lower top 4 and support 5 utilize the T-slot on the base 3 of radial drilling machine to be fixed on radial drilling machine base 3, by grinding top 7, be arranged on the main shaft 6 of radial drilling machine, take away the movable steel plate 13 on support 5, centering axle 18 is packed among support 5, again load onto again movable steel plate 13 fixing with step pin 14, the datum hole of centering axle 18 lower ends is mounted on lower top 4, adjust four and hold out against screw 13, make centering axle 18 vertical rear fixedly centering axle 18 as far as possible, move down radial drilling machine main shaft 6, make to grind top 7 datum holes that enter centering axle 18 upper ends, the set lever 19 of operation radial drilling machine, fix headstock, at this moment the position of main shaft 6 is also fixed, main shaft 6 can only move up and down and rotary manipulation,
Dial gauge is inhaled on main shaft 6, move up and down main shaft 6, in the centering axle 18 cylindricals depth of parallelism that centering bus and main shaft 6 move up and down respectively on two buses of 90 degree each other, if the depth of parallelism is overproof, by readjusting four, hold out against the direction that screw 13 is adjusted centering axle 18, repeat above-mentioned centering process, until the depth of parallelism reaches predefined precision, centering has just reached the grinding top 7 of installing on main shaft 6 and lower top 4 coaxial objects after well, and this centering process only need to be carried out once when processing with a collection of workpiece;
After centering completes, to keep the locking state of headstock, by four, hold out against screw 13 and to unclamping direction, twist 10mm simultaneously, take away movable steel plate 13 centering axle 18 is taken out.
Step 2, according to Fig. 9, the workpiece spindle 1 that needs are ground packs support 5 into, loads onto movable steel plate 13, and the centre bore of workpiece spindle 1 lower end is mounted on lower top 4, now because four hold out against the state of screw 13 in unclamping, workpiece spindle 1 can nature be swung to certain direction and in not vertical state.
Four hold out against screw 13 and now do not tighten, even if reason is with criticizing workpiece when this procedure, cylindrical also has allowance, so outside diameter has relatively large deviation, if top tight workpiece axle cylindrical, each workpiece will be adjusted, when being exactly grinding center hole, core of the present utility model do not rely on workpiece spindle excircle orientation, but the good main shaft of centering and lower top concentric in advance, locking main spindle's, automatically corrects and makes workpiece spindle 1 in vertical state when grinding by the grinding described in step 3 top 7.
Step 3, according to Figure 10, manual operation moves down main shaft 6 and makes to grind top 7 centre bores that enter workpiece spindle 1 upper end, due to the state of main spindle box in locking position, so grinding top 7 can automatically correct and make workpiece spindle 1 in vertical state, at this moment start main shaft 6 rotations, main shaft 6 drives and grinds top 7 centre bores that start on vertical state attrition process workpiece spindle 1 top of workpiece spindle 1;
Grind and workpiece spindle 1 to be turned over after the centre bore on finished piece(s) axle 1 top, again grind other end centre bore, the attrition process process of a workpiece spindle 1;
By that analogy, then change another workpiece spindle 1 and repeat said process.
